Description

Anti-collision frame for vehicle

Technical Field

The utility model belongs to the technical field of the vehicle anticollision technique and specifically relates to an anticollision frame for vehicle is related to.

Background

The rapid increase of Chinese economy leads the living standard of people to be well-developed. After the home appliances have been sufficiently popularized, the emphasis of the residential consumption is shifting to a large amount of houses and automobiles. It is with this consumer trend that the automotive industry has kept a fairly high growth rate in recent years. The increase of the owned quantity of all automobiles leads to the annual increase of the incidence rate of traffic accidents.

When a traffic accident occurs, especially when an impact accident occurs, the quality of an anti-collision beam of a vehicle is particularly important for the protection effect of the vehicle. The two ends of the existing automobile anti-collision beam are connected with low-speed energy absorption boxes with low yield strength, and then the low-speed energy absorption boxes are connected to a vehicle body longitudinal beam in a bolt mode. The low-speed energy absorption box can effectively absorb collision energy when a vehicle is collided at a low speed, and the damage of the impact force to a vehicle body longitudinal beam is reduced as much as possible. However, when the vehicle is impacted at a high speed, the anti-collision beam cannot achieve a good protection effect, and the protection effect on the driver is poor.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1 to 4, a crash-proof frame for a vehicle includes a main frame 1, a sub-frame 2 fixed to an upper surface of the main frame 1 through at least one set of fixing devices 4, two fixing devices 4 of each set, the main frame 1 and the sub-frame 2 separated and capable of sliding relatively, when the collision happens, the auxiliary frame 2 can protect people in a cab after sliding, a buffer glue layer 3 is arranged between the contact surfaces of the main frame 1 and the auxiliary frame 2 and used for increasing friction force, a bumper 5 is fixed at the front end of the auxiliary frame 2, the fixing device 4 comprises a riding bolt 41, stopping nuts 46 are installed at the two ends of the riding bolt 41 through threads, one side, close to the main frame 1, of each stopping nut 46 is provided with an elastic gasket 45, one side, close to the main frame 1, of each elastic gasket 45 is provided with a lower pressing plate 44, the lower pressing plates 44 are embedded on the riding bolt 41, and the lower pressing plates 44 are fixed through the stopping nuts 46.
